PATENT OEEICEG WILLIAM GHAPPELL, OF BUFFALO, NEW YORK.

STOVE-Pl PE TOP.

Specification forming part of Letters Patent No. 56,707, dated July 31, 1866.

To all lwhom it may concern:

Be it known that I, WILLIAM GHAPPELL, of the city ot' Buii'alo, in the county of Erie and State ot' New York, have invented a new and Improved Mode of Constructing Stove- Pipes to Prevent Smoking; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciiication, in which-- Figure lis an elevation of my improvement; Fig. 2, a plan of the same.

Likeletters ot' reference indicate corresponding parts in both iigures.

My improvement relates to that class of inventions which are employed at the top of pipes and chimneys to prevent their smoking, and is more especially designed for use on board of vesselsI to counteract the tendency of the wind to produce that heretofore irremediable annoyance; and the invention consists in the special combination and arrangement of parts hereinafter described.

In the drawings, A represents that portion of an ordinary stove-pipe which extends above the deck of the vessel, the junction at its base being formed in the usual manner, as shown in section at a, Fig. l, but so as to allow the pipe to be turned around to adapt the device to the diiferent directions of wind. B is a ring loosely surrounding pipe A, being sustained in position by braces b b, secured to the deck, as shown in Fig. 1. This ring serves as a bearing for the pipe A, and supports it in its upright position.

Near the top of A, on opposite sides, are two elbows, c c, to which are jointed the double elbows or T-Shaped pipes C O, which turn thereon, so that the cross-end pipes d d of the elbows may be adjusted in a vertical, horizontal, or inclined position, as required. The parts C O are retained in any position in which they may be placed by means of the double spring e, secured at its center in any suitable manner to the upright pipe A. rIhe ends of this spring are pointed and are inserted in any ofthe series of holesff, made in the ends of C C, so as to press against the surface of' c c within, and thereby firmly secure the T-portions in any required position in a manner to prevent their turning on the elbows c c, or from becoming accidentally disconnected from the same.

The top of A is provided with a cap or cowl, D, to Yprevent the wind from blowing down the former. In still weather this cap may be removed, if required, so as to allow an unobstructed vertical draft and escape for the products ot com bustion.

rEhe pipe A is provided at its sides with suitable handles g g, of any proper construction, by which the same may be turned on the joint a as required, which should be to such a position as-will enable the elbows O G to be so adjusted that their end portions, d d, will be in a line parallel to or coinciding with the direction of the wind. These pipes d d are adjusted in a horizont-al position, as shown in Fig. 2, the arrows denoting the direction and passage of the wind through them; or they may be slightly inclined, which is preferable, so as to give the draft throughA them an upward tendency, as shown at the right hand of Fig. l. The effect ot' a current ot' air blowing through these pipes is to increase rather than to retard the drat't from the re. The air, by friction, adhesion, and suction, carries along with it, according to the well-known principles ot'philosophy, the raretied air and gases escaping-from the tire, which meet it at the outlet which opens into the center of pipe d.

The use ot' the two T pipes or elbows O C forms a double outlet, increasing the draft, and thereby rendering the prevention and protection complete and perfect, which might not always be the case were only one of suoli pipes employed.

The simplicity, cheapness, and facility of adjusting and fixing the parts of this device in such positions that the wind cannot retard, but on the contrary increases, the draft of the smoke-pipe, peculiarly adapts it to sailingvessels, which are often obliged to change their course relative to the wind.

What l claim as my invention, and desire to secure by Letters Patent, is

The two T-pipes G C, provided with holes j' f, or their equivalent, in combination with the spring e and adjustable pipe A, provided with elbows c c the whole arranged and operating substantially in the manner set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

WILLIAM OHAPPELL.
